Extracts of raw bloody clams, broughton's ribbed ark (Scaphrca broughtonii), subcrenated ark (S. subcrenata), and granulated ark (Tegillarca granosa), were analyzed and compared foe extractive nitrogen, free amino acids, combined amino acids, ATP and related compounds, quaternary ammonium bases, and guanidino compounds. The contents of extractive nitrogen in broughton's ribbed ark, subcrenated ark, and granulated ark were 479, 506, and 432 mg/100 g, respectively. Twenty-eight or twenty-nine types of free amino acids were detected in all three extracts, among which taurine, ${\beta}-alanine$, glutamic acid, and alanine were the major ones. The composition of the major extractive components such as free amino acids, combined amino acids, ATP and related compounds, TMAO, TMA, and creatine in the extracts were similar among the extracts, but their contents were different.

피조개, 새고막, 고막으로 대표되는 고막류는 패류 중에서도 가장 중요한 수산자원의 일군(一群)이다. 고막류는 같은 과 같은 속에 속하는 패류로서 온대 및 아열대 해역에서 많이 생산되고 있으며, 전 세계에 140여종이 알려져 있으나, 우리 나라 연안에서는 위의 3종 이외에도 10여종이 더 서식하고 있다. 피조개(scapharca broughtonii)는 우리 나라 남해안 및 동해남부에 분포하며, 고막류 가운데 가장 큰 종으로서 각장 12cm에 달한다. (중략)

Purpose : To examine the effect of unilateral otitis media and unilateral cerumen occlusion of the ear canal on thermometers. Methods : One hundred eighty six children with unilateral otitis media, fifty children with unilateral cerumen occlusion, and fifty children with neither otitis media nor cerumen were enrolled. Temperature was measured in both ear canals using thermometers. After 15 minutes, second temperature was measured again in both ears. Unilateral otitis media was graded by video otoscope for 7 grades. Differences in temperatures between affected ears and unaffected ears were analyzed. Results : No temperature difference between the normal and cerumen groups was observed. The mean temperature of the otitis media ear canal was $0.13{\pm}0.20^{\circ}C$ higher than that of the intact ear canal ($36.99{\pm}0.54^{\circ}C$ vs $36.86{\pm}0.52^{\circ}C$; P<0.001). There was no statistically significant temperature difference between grades. Conclusion : Unilateral otits media can affect estimation of body temperature measured by thermometers.

고막류중에서 가장 천해성이며 조간대에 서식하는 고막은 허준의 동의보감에서도 양기를 돋우는 약재로 애용되어 왔을 뿐만 아니라 19세기 전반기부터 전라남도 순천만에서 양식이 이루어져 왔으나(배, 1986), 연안의 오염과 간석지의 매립 등으로 양식 적지가 축소됨에 따라 해마다 그 생산량이 감소되고 있는 실정이다. 따라서 고막의 어업자원을 효율적으로 관리하고 이용하기 위해서는 생태와 생활사 등 기초 생물학적인 연구가 뒤따라야 하며, 더 나아가서는 양식기술을 개발하여 생산증대 및 산업적 가치를 높일 필요성이 제기된다. (중략)

This research has the purpose to examine the potential of shell, a byproduct of maritime products to be utilized as alternative environment-friendly construction material by mixing and applying it with residual soit which is used as burial or filling material to recycle it. To that end, the research looked into the mechanical characteristics of shell through cyclic triaxial test by mixing it with residual soil. With the mixing ratios of shell of 5 groups set at 5.0%, 10.0%, 20.0%, 40.0% and 60.0%, the mixture soils was processed through a series of cyclic triaxial tests. And it was shown that liquefation resistance has limitation in the mixed soils with shell substitute content ratios exceeding 20.0%. To increase the liquefaction resistance of the mixed soil, this research has shown that addition of moderate amount of glass fibers would suffice.

As a result of compressive strength experiment, rupture compressive strength showed more increases in specimens of 15% and 20% of Cockle shells in those of non-mixture. The specimen which was used general aggregate showed the highest value and ductility capacity was getting decreased as the amount of cockle shell was getting increased in the ductility capacity of specimen. We might conclude that the reason of the yield strength's decline was the lack of the bond strength which was caused by the amount of cockle shell.

In order to effectively utilize of granular ark and ark shell, lipid and fatty acid compositions, free amino acids, nucleotides and their related compounds and minerals in the muscle and viscera of raw and cooked specimens were analyzed. The major constituents of non-polar lipids in the granular ark and ark shell were triglycerides, which showed higher content in viscera than the muscle. The polar lipids in the granular ark and ark shell were mainly consisted of phosphatidylcholine and phosphatidylethanolamine. The major fatty acids of total lipid were 16:0, 20:5n-3, 18:1n-9, 16:1n-7, 18:0 and 22:6n-3 both the granular ark and ark shell. The major nucleotides and the related compounds were adenosine monophosphate and adenosine diphosphate and they had higher content in the muscle than in viscera both samples, free amino acids such as taurine, glycine, alanine, glutamic acid, phenyl alanine and aspartic acid were abundant both the granular ark and ark shell. In the raw muscle of granular ark, glycine, alanine and $\alpha$-amino-iso-butyric acid were high level, but glutamic acid, aspartic acid and phenyl alanine were low level compared with those of cooking muscle. In the raw muscle of ark shell, taurine and $\alpha$-amino-iso-butyric acid were high content, but the glutamic acid and aspartic acid were low level compared with those of cooking muscle. Minerals in the granular ark and ark shell were chiefly consisted of potassium, sodium, magnesium, iron and calcium.

새고막(Scapharca subcrenata)은 모양이 피조개와 비슷하나 방사륵수가 29∼34줄로서 구별되며, 크기는 피조개 보다 작으나 큰 것은 각장 7cm까지 성장한다. 1970년대 말부터 양식기술이 보급되기 시작하여 1980년도의 양식생산량은 973 톤에 불과하였으나, 전라남도의 1997년도 통계자료에 따르면 연간 생산량이 49,805 톤에 달하고 있다. 새고막의 2000년도 어업권수는 912건에 양식면적은 10,629ha로서 증가 추세에 있다. (중략)

대학원생 김모씨(28세 여)는 귀에 갑작스런 통증을 느끼기 시작했다. 또 급격하게 저하된 청력으로 친구들의 말귀를 잘 못 알아들어 '사오정'이라는 별명도 얻게 되었다. 통증이 심해 병원을 찾아간 결과 외상성 고막천공이라는 진단을 받게 되었다. 이는 귀이개가 고막을 관통해 발생한 질병으로 귀이개로 귀를 후비던 중 실수고 너무 깊이 파 통증이 나타나게 된 것이다. 다행이 다른 부위는 손상이 없어 외래에서 간단한 수술 및 통원치료 후 증상은 좋아졌다. 또 직장인 박모씨(34세 남)는 어느 날부터 갑자기 귀에서 고름이 나오고, 고약한 냄새를 풍겨 병원을 찾았는데, 만성 외이도염이라는 진단을 받았다. 원인은 하루가 멀다 하고 귀지를 파내는 오래된 습관 때문이라는 것이다. 습관을 바꾸지 않으면 앞으로 청력도 떨어질 수 있다는 의사의 말에 귀이개부터 멀리하기 시작했다. 고려대 안산병원 이비인후과 조승현 교수는 "종종 속을 썩이는 것이 귀지"라며 "무리하게 후비다가는 고막까지 버릴 수 있으므로 함부로 파서는 안된다"고 지적한다.
